I always used to think those smart home water leak sensors were the most unnecessary, paranoid piece of tech you could buy. Like who actually drops money to have a little plastic puck text them when a pipe drips?
Well I was made to change my mind. A friend had a braided flexi hose split completely under his bathroom vanity while he was away for just a couple of days, and it turned his entire ground floor into an indoor pool!! The sheer amount of destruction from just a few hours of unchecked water pressure is scary, it completely warped his floorboards and ruined the plaster downstairs.
So I looked into it and yeah, things can escalate pretty fast, I read about burst pipe repair and how water mains pressure actually functions around here (Australia). Apparently those woven steel hoses have a strict lifespan and just pop without warning.
Literally bought a four-pack of zigbee sensors that same day. So if you have older plumbing fixtures or haven't checked under your sinks in years, just go look at those hoses before they ruin everything!
